Appearance

Playground ​

The durable-agents-playground is an example application demonstrating DARIX patterns. Located at examples/durable-agents-playground/ in the repository.

What it includes ​

14 agent types organized into four categories.

Standalone ​

  • assistant --- general-purpose agent with calculator, database, memory, dice, and inventory tools

Coordination ​

  • worker --- generic configurable child agent (prompt and shared state via spawn args)
  • deep-researcher --- spawns specialist sub-agents for deep research
  • manager-worker --- multi-perspective analysis (optimist/pessimist/pragmatist)
  • dispatcher --- routes tasks to the appropriate agent type
  • pipeline --- sequential worker stages
  • map-reduce --- parallel chunk processing

Blackboard (shared state) ​

  • debate --- pro/con workers with shared argument state
  • peer-review --- multiple reviewers evaluating an artifact
  • wiki --- 7 category specialists building a knowledge base
  • trading-floor --- traders with shared market state

Reactive ​

  • summarizer --- observes entity streams, produces summaries
  • monitor --- watches multiple entities, reports status changes
  • guardian --- quality control observer

Running it ​

bash
cd examples/durable-agents-playground
pnpm install
cp ../../.env.template .env  # Set ANTHROPIC_API_KEY
pnpm dev

Requires a running DARIX server at http://localhost:4437 (default).
